2) Nut driver for output connectors Please report any damage or missing parts to your dealer immediately. Place the P-303 at or near its final set-up position, allowing 8 inches at the rear for tightening the speaker output connectors. The power transformer in the P-303 is located at the front-center of the unit. Ideally, a few feet should separate this area from components which potentially could pick up hum. -
Page 5: General Connections
Input and output connectors are clearly marked on the back of the amplifier. Left/Right connections are oriented from the front of the unit. Stereo output connections are marked above the connectors. Switch stereo/mono switch to STEREO position. (The P-303 is preset at the factory for STEREO.) Use only high quality interconnect and loudspeaker cables, and make all connections tight. - Page 6 Correct output phase MONO connections are marked below the connectors. Repeat the above MONO settings and connections on the second P-303 to be used for the other channel. Please remember that the negative output connection of a bridged amplifier is NOT a ground.
- Page 7 CA-301 ISSUE 1 MAY ‘99 MONO OPERATION As stated above, either the regular or balanced inputs can be used in stereo or mono. Connect a single interconnect, either regular or balanced, to the left channel input of each amplifier. See the "Mono" section above for complete details. NOTE: Neither the Stereo-Mono switch nor the switch will operate while the amplifier is turned on.
